Leonard returns from his North Sea expedition to find that his relationship with Penny involves more beta-testing than he's ever done in a lab. Howard's attachment issues with the women in his life in particular and Raj's social breakthrough with women in general provide more laughs. Bernadette and Amy stand staunchly by the men in their life, even when they're sitting in marathon role-playing games.
